The TQXmlErrorHandler class provides an interface to report
errors in XML data.
< p >
< p > If you want your application to report errors to the user or to
perform customized error handling, you should subclass this class.
< p > You can set the error handler with < a href = "qxmlreader.html#setErrorHandler" > TQXmlReader::setErrorHandler< / a > ().
< p > Errors can be reported using < a href = "#warning" > warning< / a > (), < a href = "#error" > error< / a > () and < a href = "#fatalError" > fatalError< / a > (),
with the error text being reported with < a href = "#errorString" > errorString< / a > ().
< p > See also the < a href = "xml.html#sax2Intro" > Introduction to SAX2< / a > .
< p > < p > See also < a href = "qxmldtdhandler.html" > TQXmlDTDHandler< / a > , < a href = "qxmldeclhandler.html" > TQXmlDeclHandler< / a > , < a href = "qxmlcontenthandler.html" > TQXmlContentHandler< / a > , < a href = "qxmlentityresolver.html" > TQXmlEntityResolver< / a > , < a href = "qxmllexicalhandler.html" > TQXmlLexicalHandler< / a > , and < a href = "xml-tools.html" > XML< / a > .

< / h3 >
< p > A reader might use this function to report a recoverable error. A
recoverable error corresponds to the definiton of "error" in
section 1.2 of the XML 1.0 specification. Details of the error are
stored in < em > exception< / em > .
< p > The reader must continue to provide normal parsing events after
invoking this function.
< p > If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function < a href = "#errorString" > errorString< / a > () to
get the error message.
< h3 class = fn > < a href = "ntqstring.html" > TQString< / a > < a name = "errorString" > < / a > TQXmlErrorHandler::errorString ()< tt > [pure virtual]< / tt >
< / h3 >
< p > The reader calls this function to get an error string if any of
the handler functions returns FALSE.
< h3 class = fn > bool < a name = "fatalError" > < / a > TQXmlErrorHandler::fatalError ( const < a href = "qxmlparseexception.html" > TQXmlParseException< / a > & exception )< tt > [pure virtual]< / tt >
< / h3 >
< p > A reader must use this function to report a non-recoverable error.
Details of the error are stored in < em > exception< / em > .
< p > If this function returns TRUE the reader might try to go on
parsing and reporting further errors; but no regular parsing
events are reported.
< h3 class = fn > bool < a name = "warning" > < / a > TQXmlErrorHandler::warning ( const < a href = "qxmlparseexception.html" > TQXmlParseException< / a > & exception )< tt > [pure virtual]< / tt >
< / h3 >
< p > A reader might use this function to report a warning. Warnings are
conditions that are not errors or fatal errors as defined by the
XML 1.0 specification. Details of the warning are stored in < em > exception< / em > .
< p > If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function < a href = "#errorString" > errorString< / a > () to
get the error message.
